I have worked with PCB Fab Express with verry good quality and fast turnaround.

But there is a company in Chicago that makes all kinds of wired looking boards, I mean round, or leaf like, whatever you need it to be and with different colors solder mask and asorted silk screen. Take a look at Pulsar Inc.

The best in-country house I've found is www.sunstone.com, formerly PCBexpress. Best quality boards I've seen, and lowest prices I've found. (For the quality i'd want at work)

Now did you mean the PCB fab, or the whole assembly including components?

I've seen Sunstone has a deal with another company (called screaming circuits) for complete turn-key assembly with components and all, but I never tried that before. But if it matches Sunstone board quality, it'd be a good bet.

I use Screaming Circuits at work. However, you can probably have it done cheaper by overseas assemblers like bittele , goldphoenix, myropcb. They have sales offices in North america as well.

One of my colleagues just had a shipment delivered from bittele yesterday. Haven't had time to discuss with him about the quality of the boards, but they look good, they were well packaged, the price was reasonable, and they came pretty quickly considering they were made in china.
